【 摘 要 】

The synthesis of sodium aluminosilicate solids phases precipitated from NO{sub 2}/NO{sub 3}-free and NO{sub 2}/NO{sub 3}-rich liquors has been performed. Four sodium aluminosilicate precipitation products were formed. These are (1) X-ray/electron diffraction-indifferent amorphous phase; (2) crystalline zeolite A; (3)NO{sub 2}/NO{sub 3}-rich crystalline sodalite; and (4) NO{sub 2}/NO{sub 3}-rich crystalline cancrinite phase. Characterization of the physicochemical properties for these phases has been performed under conditions simulating Westinghouse Savannah River Company liquid waste processing.
